SHEET-METAL ROOFlNG PLATE.

- QPEGIPICATIQN forming part of Letters Patent No. 307,590, datedNovember a, 1884.

' Application filed May 28, 1884. (X0 model) To aZZ whom it may concernBe it known that I, PATRICK HENRY RE- GAN, of Nashville, in the countyof Davidson and State of Tennessee, have invented certain new and usefulImprovements in Sheet-Metal RoofingPlates, of which the following is afull, clear, and exact description.

The obj eet of my invention is to provide inexpensive and durableroofing-plates which may be quickly laid and will be weathcrproof inheavy storms.

The invention consists in peculiar constructions of the joints of theplates to provide for easy locking together of the plates withwator-proof joints, which will not be broken or split by pressure ortension, and will provide for expansion and contraction of the roofingby changes of temperature.

The invention consists, also, in peculiar formations of the face of theroofing-plate to deflect the downflowing water toward the centers of theplates and away from their joints, and in other details of construction,all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 represents my improved roofing plates as applied to a roof andpartly broken away. Fig. 2 is a transverse section through two adjoiningplates taken on the line xx, Fig. 1.

The letter A indicates the rooting-plates, which are formed along oneedge with a flange, B, perforated to receive the nails (1, by which thatedge of the plate is fastened to the roof of the building, railway-car,or other structure. Along the flange B the metal of the plate is bent toform the bead C, whence the plate runs along laterally for a distance,as at 0, about in line with the general bottom surface of the platewhich lies upon the roof, and from the point d the plate is bent overtoward the bead G and back again to form the lip D, which overhangs thepart c, and provides a narrow space, 0, between the parts 0 D, in whichthe flange E, along the opposite side edge of the next roof-plate to theright, is adapted to be passed, as at the center of Fig. 2. The rise ofthe metal of the plate to form the lip D provides for forming along thelip the shoulder or incline F, which drops to the general level of theplatesurface at f, whence the plate continues laterally at g to acentral bead, G, which has a half-round enlargement,h, at each side nearthe central lower edge of the plate, forming a raised surface orcorrugation, H, of circular general form. From the bead G andcorrugation H the plate takes itsgeneral level, as shown at z, whencethe plate-surface rises in an incline, I, beyond which is formed thebead or corrugation, J adapted to overlap the bead or corrugation G atthe other or right-hand edge of the adjacent plate A, While the flange Einterlocks with the lip D of the said plate. Segmental-shaped raisedsurfaces or corrugations K are formed in the plate A, with their roundedsides or edges 70 facing each other and the central head or corrugation,G, an d their straight edges or chords k facing the opposite inclinedsurfaces, F I, of the plate. Along the upper ends or edges of the platesA they have raised surfaces L between the side inclined surfaces, F I,said surfaces or corrugations L corresponding in width with the lap ofthe lower ends of the next upper horizontal row or layer of the plates,and the lower ends or edges of the plates A are crimped or bentdownward, as at M, to come upon the faces of the next lower row ofplates just below the lower transverse edges, l, of the corrugations L,as in Fig. 1.

In laying the roof-plates, their right-hand edges are made fast bynailing the flanges B to the roof, and the left-hand edge of the next orright hand plate is locked to the plate last laid by slipping the flangeE of the right-hand plate into the space 0 beneath the lip D of thenailed lefthand plate, whereby the bead J of the plate being laid willlook over the bead O of theother plate, whereupon the flange B of theright-hand plate may be nailed fast at a, ready to receive beneath itslip D the flange E of the next roofing-plate, and so on for the wholewidth of the roof. As the successive horizontal rows of plates are laid,the central beads or corrugations, G, and the left-hand beads orcorrugations J will alternately line with each other down the roof, sothat the downfiowing water will take a course mainly inward from theinclined plate-faces F I, and

around the curved edges 70 of the corrugations K toward the centralbeads, G, of the successively lower roof plates, and thus deflect orguide the water away from the joints of all the plates and avoidflooding the joints, thereby lessening the liability of the roof to leakduring heavy rain or snow. storms. Each course or row of the plates A isfinished as it is laid, avoiding damage to the finished roof by walkingon it, and walking over the plates only tends to close the joints of theplates more tightly; and in laying the plates no hammering or malletingof the joints is necessary, and by forming the jointsby the curved bentbeads, lips, and flanges, as described, every necessary provision ismade for the free contraction and expansion of the plates by changes oftemperature and to guard against the cracking or splitting of the platesby pressure or tension. Moreover, my improved roofing-plates may quicklybe laid, and by unskilled labor, and make a cheap and reliable roof.

I am awarethat roofing-plates have before been made which have along oneside or edge a nailing-flange, and next to it a raised gutter, and thenan overhanging lip, which flange, gutter, and lip are covered by araised cap formed on the opposite edge of the adjacent plate, whichisbent down to lock under the overhanging lip from the top, as shown inthe patent to J. Walter, No. 256.083, dated April 4:, 1882. In myplates, the lock flange E be ing held beneath the overhanging lip D andthe bead 0, inside of the flange E, insures protection against leakage.It will also be seen that the lock-flange E is entirely protected by thelip D from winds blowing in one direction,

ing-plates adapted to be arranged with other similar plates inoverlapping courses orlayers,

and formed at their one edge with a flange, B, a bead, C, and a lip, D,formed so as to overhang toward said head and nearly inclose a narrowspace, 6; and said plates being formed at the opposite edge with thebead J and flange E, adapted, respectively, to overlap the bead O andenter the space 6 of the adjoining plate, substantially as shown anddescribed 2. A sheet-metal roofing-plate having one of its edges formedwith a nailing-flange, B, a bead, O, and a lip, D, overhangingtowardsaid bead and nearly inclosing a space, 6, below the lip, andhaving its opposite edge formed with a bead, J, and lock-flange E,substantially as shown and described.

3. A sheet-1netalroofing-plate formed with a central bead, G, having anenlargementat H, near the bottom of the plate, and'formed, also, withsegmental raised surfaces K K at each side of the bead G, and arrangedwith their curved edges la la facing the bead, sub

5. A sheet-metal roofing-plate formed with a nailing-flange, B, bead O,lip D, space 6, and incline F along one edge, and a bead, J,locking-flange E, and incline I along the opposite edge, also with acentral bead, G, having an enlargement, H, segmental raised surfaces KK, arranged with their curved edges k k facing the bead G, a raisedsurface, L, along the top of the plate, and a depression, M,at the loweredge of the plate, substantially as shown and described.
